BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The invention herein of a self-assembled spherical jointstructure mainly provides a spherical joint structure not limited by theposition and the order of assembly but capable of enabling the user toquickly identify the correct mounting holes to be connected with thesupporting rods extending to various directions; more especially, everysingle spherical joint has the same external shape and the same mountingmethod for the mounting holes and is exchangeable to not only enhancethe speed and convenience of assembling, but also reduce the moldingcost of manufacturing the spherical joint.

[0003] 2) Description of the Prior Art

[0004] As shown in FIG. 1 of the isometric drawing of the assembledframework of the conventional beam structure, the entire beam frameworkstructure is constructed by a spherical joint (A) connected with thesupporting rods (B), wherein the supporting rods (B) are lapped invarious directions according to the specific configuration required; themain function of the spherical joint (A) is to have pre-mounted mountingholes (A1) facing specific directions to comply with the need of theincluded mounting angles of the supporting rods; when assembling thebeam framework structure, the end portion of every supporting rod (B)has to be fixedly inserted into the specific mounting hole (A1) on thespherical joint according to the order of the predetermined andpre-calculated plan to connect all the supporting rods into thestructure of the desire beam framework.

[0005] However, the structure of the beam framework aforementioned isnot limited to the architectural design only, by connecting thespherical joints with the supporting rods, the simple assembly withcertain structural strength can be widely applied in the ordinary life,for examples, as a storage shelf, an exhibit cabinet, a table, a chair,etc. assembled in proper shapes to comply with the specific requirement;however, in order to be convenient for the drilling of various degreesof angles, the external shape of the conventional spherical jointappears as a round ball; furthermore, since every mounting hole isdrilled according to a specific degree of angle, the mounting method ofthe included angle of every mounting hole on the spherical joint will bedifferent; therefore, every spherical joint with its won specificmounting order and position not capable for exchangeable connection notonly reduces the variation of the entire structure of the beamframework, but also fails to meet the need of space alternation requiredby the user; furthermore, the smooth external ball shapes of the all thespherical joints make the distinguishing of each mounting holedifficult, that increases the trouble and the inconvenience ofassembling.

SUMMARY OF THE INVENTION

[0006] Therefore, the invention herein of a self-assembled sphericaljoint structure, by designing the entire external shape of the sphericaljoint as a spherical structure of a multi-angular spheroid with multipletangent planes of six cubical quadrilateral and twelve beveled hexagonaltangent planes connected among the side lines of the six quadrilateraltangent planes, and with mounting holes disposed respectively at thecenters of the quadrilateral and the beveled hexagonal tangent planes tomake each spherical joint have eighteen mounting holes with includedangles pointing at different directions to increase the application of asingle spherical joint and to make the structures of all the sphericaljoints the same for exchangeable connection, has the main objective ofnot only complying with the needs of specific application, but alsobeing capable of making various applications to meet the requirement ofspecific assembly for the alternation of different degrees of mountingangles.

[0007] Another objective of the invention herein of a self-assembledspherical joint structure is to use the external design of the polygonalsphere to distinguish the tangent planes of all the mounting holes intothe shapes of squares and hexagons to allow the user to quickly identifythe positions of desired mounting holes for assembling so as to increasethe precision and convenience of assembling.

[0008] Yet another objective of the invention herein of a self-assembledspherical joint structure is to thread the inside of the mounting holeson the spherical joint for the structural need of the supporting rods toprovide the fixedly fastening of the threads on the end portion of thesupporting rod to enhance the connection strength among all thesupporting rods.
